Units of area per person for specific buildings can be found in the chart at the end of this article. There is a common misconception about the “Maximum” Occupant Load table in the International Building Code. 100 gross Waiting areas. The occupancy load is calculated by dividing the area of a room by its prescribed unit of area per person. Step 3 Work the calculations: Square footage of the use divided by the “Occupant Load Factor” = maximum capacity. 7.3.1.1 The total capacity of the means of egress for any story, balcony, tier, or other occupied space shall be sufficient for the occupant load thereof. 11 gross Exhibit gallery and … will have different load factor ft. 75 divided by 5 = 15; Occupant load of 15; Total Occupant Load of 50 (35 + 15) Note: If the occupant load calculations are to ensure compliance with the Governor’s executive order related to COVID -19 (50% occupancy and no more than 250) divide the total occupant load above by two and round up. The occupant load factor changes based on the relevant classification of the area. Figure 1. Additional occupiable space (for example, a waiting area) is calculated using the occupant load factor for that space, which is then added to the number of fixed seats. (not including storage rooms): 800/100 + 90/15 = 14 persons Phase 2 Re-opening would further limit the total to 50% or 7 persons. NYC Building Code 2014 > 10 Means of Egress > 1004 Occupant Load > 1004.1 Design Occupant Load > 1004.1.2 Modifications 414.2.2 Special Detailed Requirements Based on Use and Occupancy, Number The maximum number of control areas within a building shall be in accordance with Table 414.2.2. If you don’t live in the life safety arena, this change allows the calculated occupant load for a business space to be notably less, thereby requiring less exit width, stair width, potentially the number of exits, and other means of egress requirements. determined by measuring the areas, dividing by the occupant load factors for each area, and adding the numbers together. The occupant load factor is one person for each 40 ft (3.7 m ) of gross floor area of c sales space. Example of occupant load determination The following is an example of an assembly venue with multiple uses. Waiting areas Baggage claim Baggage handling Gaming floors (keno, slots, etc.) Occupant load = Number of fixed seats Occupancy load = 15’ x 15’ = 225 Assembly no fixed seat = 7 225 / 7 = 32 Occupancy load = 15’ x 20’ = 300 Assembly Unconcentrated = 15 300 / 15 = 20 Occupancy load = (30’ x 40’) – (15’ x 20’) = 900 Business area = 100 900 / 20 = 9 Total design occupancy load = 32 + 20 + 9 = 61. 1004.1.1.2 Adjacent levels for mezzanines. For the purpose of determining occupant load in mercantile occupancies with no street floor, as defined in 3.3.239, but with access directly from the street by stairs or escalators, the floor at the point of entrance to the mercantile occupancy is d considered the street floor. Determine the “occupant load factor” for those areas. Seating for benches without dividing arms (for example, bleachers) is calculated at 18 linear inches of seating length per person. Gross floor area Figure 2. I made the default value 0, and that value means that the Area/Occupant Load value should be calculated, if possible, and used as the RESULT. 1004.7 Fixed seating. The occupant load of any space shall include the occupant load of all spaces that discharge through it in order to gain access to an exit. This table list the number of occupants per square foot that you are designing to rather than a true maximum. 300 gross Concourse. The “occupant load factor” is defined as the allowable floor area in square feet per occupant. A copy of Table 1004.5, which is from the Uniform Code, is at the bottom of this article. The occupant load shall be calculated by the greater of the following methods: 1. The occupant load, in number of persons for whom means of egress and other provisions are required, shall be determined on the basis of the occupant load factors of .

Airport terminal Baggage claim. 20 gross Baggage handling. occupant load density of an area, except as provided for in Section 1004.2, but once the occupant load is established, the means of egress must be designed for at least that capacity. ICC Digital Codes is the largest provider of model codes, custom codes and standards used worldwide to construct safe, sustainable, affordable and resilient structures. Use the floor plan (preferably a scale drawing or at least with room and area dimensions) and calculate the occupant load for the areas used by the patrons of a business as follows: Moveable Seating: Fixed Seating: Floor area in square feet divided by factor of 15. Here's a general overview of how it's done. 500 gross. For Assembly occupancies with fixed seating, the seats are counted to determine the occupant load. in accordance with Chapter 10 requirements and complete a Form A. OCCUPANT LOAD FACTOR a. Accessory storage areas, mechanical equipment room. https://idighardware.com/2014/07/decoded-calculating-the-occupant-load Several additional occupant load factors are listed for Assembly occupancies without fixed seating. As an example, the table lists 100 gross sf per occupant in a business occupancy. by using the appropriate occupant-area ratios from table 6-2, whichever is larger. Various events, such as discos, conferences, dining facilities etc. booths or free moving tables and chairs), 200 sf of waiting area of standing space and 800 sf kitchen. 300 gross.

Occupant load of 35; Waiting area (5ft x 15ft) = 75 Sq. Note: this is for patrons and customers; staff are not included in these limits. 5 2. Since the occupant load factor is for offices, the standard factor is 100 square feet for all business use.

Plan check engineer will place the "Determination of Assembly Occupant Loads – Parking" stamp on each of the four sets of plans and complete all required information. - Where data regarding the sq. Calculating the Occupant capacity This is related to hall size and density of people within the available floor space) When the hall is in use an occupant load factor value (m² per person) is introduced, in relation to the floor area being used. That por- tion of the occupant load of a mezzanine with required egress through a room, area or space on an adjacent level shall be added to the occupant load of that room, area or space. The 2018 Edition of NFPA 101 has updated the long-held occupant load factor of 100 sqft per person to 150 sqft per person. For instance, the chart dictates that dormitories require 50 square feet of floor area for every room occupant. Table 7.3.1.2 that are characteristic of the use of the space or shall be determined as the maximum probable population of the space under consideration, whichever is greater. = Occupant Load of Area gross net V/SqFt Concourse For areas having fixed seating without dividing arms, the occupant load shall not be less than the number of seats based on one person for each 18 inches (457 mm) of seating length. Additional occupiable space (for example, a waiting area) is calculated using the occupant load Assembly Gaming floors (keno, slots, etc.) NOTE: If the occupant load calculations are for compliance with the Governor’s Executive Order for COVID-19 (25% occupancy), divide the total occupant load determined above by 4 (total would be 3 for existing and 2 for new). Except in Use Group A-2 (nightclubs), the occupant load may be equal to the total number of occupants for whom exit capacity is provided as determined by (f)1 above. this occupant load. Standard occupant calculation per section 1004 NCBC 2. The occupant load factor changes based on the relevant classification of the area. 30 net Billiard table/game table area. Find the two widest areas of the room and multiply them; this should approximately give you the total floor area. The maximum permitted occupant load of a given space shall be determined by dividing the floor area for a given use by the occupant load factor in Table 5:70-4.11(f)3. i. 3. Plan check engineer will determine the minimum design occupant load for each area (including office, bar, waiting area, kitchen, etc.) Estimate the net floor area by referring to the office blueprint. For areas having fixed seats and aisles, the occupant load shall be determined by the number of fixed The occupant load is determined by measuring the areas, dividing by the occupant load factors for each area, and adding the numbers together. occupant loads of all rooms, areas or spaces to that point along the path of egress travel.
